Title: Connecting and resetting devices
Inventor: HANNO BECKER
IPC: H04W4/70
Filed: 2020-05-06
Abstract: A method for managing a connection between a device 20 and a server resource 30 comprises: establishing the connection between the device and a server 38-1 of the resource; registering a related connection identifier (CID) in a database entry 42 of a database arrangement 40; pre-computing, at the server, an encrypted alert 48 for the device, the alert being provided with a pre-defined future communication sequence number 50 (e.g. 0x00FFFFFF); and transmitting the alert from the server to the database arrangement for storage in association with the database entry. The connection may require security parameters generated using an authentication key exchange protocol such as a datagram transport layer security (DTLS) handshake. If it is determined that the connection is to be reset, possibly due to a fault in the server, the alert may be sent from the database to the device via a second server 38-2, and a new connection established. The method may be used with temperature sensors, healthcare monitors and electronic door locks forming part of an Internet of Things (IoT). The battery lifetime and reactivity of devices may be extended by using connection identifiers and DTLS connections which may persist for the lifetime of devices.

Title: Handling of distributed ledger objects among trusted agents through computational argumentation and inference in the interest of their managers
Inventor: ALBERTO RIGOTTI
IPC: G06Q10/10
Filed: 2020-06-09
Abstract: A method and system for the handling of distributed ledger objects among trusted agents through computational argumentation and inference in the interest of their managers, where a trusted agent, the protagonist, after a selection and identification phase, initiates a dialogue with other trusted agents, the antagonists, proposing an argument to justify the acceptance of a claim aiming to obtain the handling of distributed ledger objects in the interest of its manager. The antagonists may or may not decide to be engaged in a negotiation with the protagonist depending on their claims with their given constraints and limits. In the former case they exchange arguments and counterarguments with the other trusted agents involved and through computational argumentation and inference they agree on the handling of distributed ledger objects by subscribing a contract and performing it in a distributed ledger. Each agent is unequivocally associated to its manager and each agent exchanges a cryptographic secret derived from its root of trust module to identify itself as trusted (authentication).

Title: Gate Driver
Inventor: SIMON DAVID HART
IPC: H03K17/16
Filed: 2019-11-26
Abstract: A gate driver for a semiconductor power device and a method of driving the gate of a semiconductor power device. The current flowing through the semiconductor power device, caused by a first gate drive voltage during the present switching cycle, is sensed. Based on a second drive signal to be used in the next switching cycle, a second current is determined for that second drive signal, which are then compared to an EMC model. The EMC model defines a plurality of EMC values for respective gate drive voltages and currents conducted through the semiconductor power device. A gate drive voltage adjustment value is selected from a plurality of gate drive voltage adjustment values in the EMC model based on the predicted EMC value generated by the semiconductor power device when being driven using the second drive voltage and conducting the second current. The second gate drive voltage is adjusted using the selected gate drive voltage adjustment value for the next switching cycle.

Inventor: Shigehiro Nagano
IPC: G02B6/13
Filed: 2019-05-24
Abstract: The present invention provides a method for manufacturing an optical device. The method for manufacturing an optical device includes a laser impingement step of focusing first pulsed laser light and second pulsed laser light inside a glass material containing germanium and titanium to thereby cause a photoinduced change in the refractive index of the glass material and a focus position movement step of moving the focus position relative to the glass material. The first laser light and the second laser light both have a cyclic frequency of 10 kHz or greater. In the laser impingement step, the first laser light is focused in an intermittent focus region and the second laser light is focused in an annular focus region surrounding the focus region for the first laser light. The center wavelength of the first laser light is greater than 400 nm and less than or equal to 700 nm, and the center wavelength of the second laser light is greater than or equal to 800 nm and less than or equal to 1100 nm. A continuous refractive-index variation region may be formed by alternately repeating the laser impingement step and the focus position movement step or performing the steps concurrently.
